Stratigraphy
| Formation: | Mikindani | ||||
| Local section: | Lindi | ||||
| Stratigraphic resolution: | bed | ||||
| Stratigraphy comments: Pliocene strata. The Mikindani Formation is essentially fluviatile, and is by no means certainly correlatable across Tanzania. The layers include sandy clays, marls, marly limestone and sands, both macrofaunas and microfaunas are richly developed. | |||||
